Thank you again! The first attempt with chartread gave 10-15 faults during
reading but the second only two! It's selflearning. As the paper I tested
to profile has a lot of OBA I used the FWA-compensation in Argyll (-f
D50M2) when I made the profile as the i1 Pro I have has no UV-filter.
Profile check with my 720 patch chart (I changed A4 to 297x210 to be able
to read with the ruler) gave this profile check: peak err = 1.38, avg err =
0.38, RMS = 0.45. I think this is a very good result! I used -f D50M2 as
FWA compensation. Is there any difference using only M2?
